PAPER BOTTLE.

Specification of Letters Patent.

Patented Dec. 7, 1909.

Application filed January 2, 1909. Serial No. 470,541.

To all whom it may concern:

Be it known that I, ltonnn'r LUNnnLL, a citizen of the United States, and resident of New York, borough of Manhattan, county and State of New York, have made a new and useful Invention in Paper Bottles, of which the following is a specification.

hly invention is directed particularly to an improvement in paper bottles such, for instance, as is disclosed in U. S. patent to J. H. Hanks, No. 667,218, granted February 15th, 1901, and it has for its objects, first, to provide a bottle of this nature in which both the bottom and neck parts thereof shall be materially strengthened; second, to provide such a bottle having an exterior neck ring, preferably of metal, which will not only strengthen the neck or mouth of the bottle but will afford at one and the same time a means for more easily opening it when it is desired to use the contents thereof, and will also afford means adapted to form a throat near the mouth for effectually sealing the inclosing cap or cup; third, to provide a bottle of this nature in which the mouth thereof is expanded in such manner as to permit of the insertion of an inclosin stopper, cap, or cup, which cup may be effectually hermetically sealed through the agency of a crimping machine; fourth, to provide a bottle of this nature in which both the bottom and the inclosure for the mouth are composed of paper or equivalent caps or cups which are connected to the walls of the bottle proper through the agency of a crimping machine, thereby materially decreasing the cost of the completed bottle and, at the same time, affording an article which is hermetically sealed at both ends; fifth, to provide a bottle of this nature in which both the body part of the bottle and the inclosing ends at the bottom and the mouth thereof are constructed entirely of paper and provided with strengthening means so located in conjunction with said parts that the entire bottle may be hermetically sealed throu h the agency of a crimping machine; sixt to provide a neck rin on such a bottle which constitutes an indlcator or a guide for cutting the cap 03 with a knife.

For a full and clear understanding of my invention, such as will enable others skilled in the art to construct and use the same, reference is had to the accompanying drawings, in which,

Figure 1 is a sectional view taken through my improved bottle during the first stage of the making thereof, the neck or upper end being illustrated in dotted lines as in its expanded form. Fig. 2 is a view similar to Fig. 1 illustrating the rigid holding and indicating neck ring and the manner of utilizing the same in expanding the mouth of the completed bottle, so as to form a seat in the throat in which the inclosing cap or cup may be secured. Fig. 3 is a sectional "iew of the completed bottle; and Fig. 4 a sectional view of the complete inclosing cap or cup located above the bottle ready for insertion therein. Fig. 5 illustrates in sectional view the bottle as it appears when filled and hermetically sealed ready for shipment or use.

Referring now to the drawings in detail, 1 represents the body part of a bottle made of paper or equivalent fibrous material and having preferably the form of a 'frustum of a cone; 2 the bottom cup for inclosing the lower end thereof, said cup having been formed in the usual way by the a pplicatiou of pressure and heat in a die and inserted within the bottom of the body part 1, bot tom upward, in the manner shown.

3 represents a strengthening disk made of heavy pasteboard or any equivalent material of greater strength than the bottom of the cup 2.

4 represents a neck ring of wire or of strip metal and having preferably the conformation shown in Figs. 2, 3 and 5, said ring assuming, when in place, the position shown in said figures.

5 represents a strengthening disk for the inclosing cap or cup 6 which cup is formed in the same manner as was the cup 2 and is provided with a strengthening disk 5 corresponding to the similar disk 3 for the bottom cup.

In the formation of this bottle the body part thereof is constructed in the usual manner by forming a cone-shaped tube having its edges secured together in any preferred way, the bottom cup 2, together with the strengthening disk 3 being inserted in the manner shown in Fig. 2, and while in this position the mouth or throat is eggpapded outwardly by a heated dicated by the dotted lines XX Figs. 1 and 2, thus forming a throat and a seat for the sealing cup or cap 6, so that the entire month of the bottle assumes when completed n N mmg tool, as mi the conformation shown in Fig. 3. The bottom of the bottle is then placed in a crimping machine of well known form, the lower end of the body part being turned upward so as to form a double fold, as shown. In doing this, however, it will be noted, that with my improved bottle the bottom thereof is not only materially strengthened because of the disk 3 and the double folds of the lower portion of the body part 1 and the turneddown edge of the cup 2, but all of the parts are thus effectually hermetically sealed together in such manner as to give the best possible ef fects as to strength and capacity for holding a liquid, the disk 3 being seated on the upper edge of the crimped edge of the body part. The bottle is then filled and the inclosing cap or cup 6 is inserted by forcing the same downward from the position shown in Fig. 1 into the mouth thereof, so that the edges of the cup 6 are concentric with the edges of the mouth, the strengthening disk 5 being securely held in the throat just above the top of the neck ring 4. The parts are then sub jected to a crimping machine so that the mouth is closed and the entire bottle with its contents hermetically sealed in the manner indicated in Fig. 5, the lower edge of the crimped part of the neck being seated against the strengthening disk 5. The bottle may be made of individual parts, either where they are assembled or elsewhere, and these parts may be water-proofed with paraflin or any equivalent liquid waterproofing agent before they are put together. It is preferable, however, to delay the waterproofing process until the bottle has assumed the completed form shown in Figs. 3 and 5, the final water-proofin of the completed filled bottle shown in Fig. 5 effectually hermetically sealing the inclosed contents.

I do not limit my invention to the specific structural bottle disclosed in the accompanying drawings, although the bottle thus illustrated discloses a structure which possesses the especial points of utility it is desired to effect.

My claims are generic as to the feature of the exterior neck ring near the month which is of such formation or shape as to give to the interior surface of this portion of the bottle a throat like effect within which the inclosing cap or cup may be seated, and with the greatest possi le strengthening effect, such a ring acting, as before stated, as a means of indication and assistance for opening the bottle or getting at the contents thereof, and this may be effected by inserting the point of a knife blade through the neck above the ring and then using said ring as a guide to sever the neck from the bottle proper. It is also obvious that with such a strengthening ring and expanded throat any cork, wooden or other stopper might be used, if preferred, in place 0 a sealable cup,such a ring giving the necessary strength to the throat to permit of its in sertion without rupturing the mouth.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is 1. As an article of manufacture a paper bottle embracing a body part having a bottom secured thereto; together with a strengthening ring located around the neck and below the mouth, substantially as described.

52. As an article of manufacture a paper bottle having a body part of the form of the frustum of a cone; a bottom in the na ture of a cup secured thereto by an inwardly turned crimp; together with astrengthening ring around the neck, the latter increasing in diameter from said rin toward the mouth, substantially as descri ed.

As an article of manufacture a paper bottle having the form of a frustum of a cone and a strengthening ring located around the neck and below the mouth, substantially as described.

4. As an article of manufacture a paper bottle having the form of a frustum of a cone; a bottom secured within the base thereof by an inwardly extending crimp; together with a strengthening ring about the neck; said rin being held in place by an enlarged extension of the upper end of the body and acting as a guide to sever the neck from the body when it is designed to use the contents, substantially as described.

5. As an article of manufacture a paper bottle having a body part which diminishes in size from the bottom thereof to the base of the neck said neck expanding continuously to the mouth; to other with an inclosing ring held in place etween the neck and the body part, su stantially as described.

6. As an article of manufacture a paper bottle having a body part and an expanded neck; together with a metal rin held in place between the two, snbstantia ly as described.

7. As an article of manufacture a paper bottle having a body part which diminishes in size from the bottom thereof to the base of the neck, said neck expanding outwardly to the outer end of the mouth and surrounded by a metal ring; together with a cup shaped cap and a strengthening disk, said cap being held in seated position by the inwardly turned ed e of the mouth, substantially as describe In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
